LAGQUERING-MAGHINE FOR CANS.

Specification of Letters Patent.

Patented April 27. 1909.

Application filed June 9, 1908. Serial No. 437,500.

To all whom it may concern: r 1

Be it known that I, OLAUDEB. HANTHORN, i a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented a new and. Improved Lacquering-Machine for Cans, of which the following is a full, clear, and exact description.

This invention relates to a machine for the purpose of lacquering cans.

The object of the invention is to produce to receive cans which are fed to it, in such a way that the cans will be dipped in a bath of lacquer and dried before delivery from the machine. I v

The invention consists in the construction and combination of'parts tobemore fully particularly set forth; in the claims.

Reference is to be had to the acconipany ing drawings forming a part of this specification, in which similar characters of reference indicate co responding parts in all the figures.

Figure 1 is anend elevation of a machine constructed according to my invention; Fig. 2 is a cross section through the feed chute, taken on the line 2-2 of Fig. 1; Fig. 3 is a vertical section taken on the line 3-3 of Fig. 5; Fig-.4 is a vertical section upon an enlarged scale, taken at the point where the cans are dipped in the \bath Fig. 5 is a cross section through the machine, taken on the line 5-5 of Fig. 3 and Fig. 6 is a view showing a part of thedipping plate in plan, and showing a portion of the feed chute in cross section on the line 66 of Fig. 5 and indicating the manner in which the cans are fed to the machine. 7

Referring more particularly to the parts, and especially to Figs. 1, 3 and 5, 1 represents the frame of the machine. This frame is formed of circuinferentially disposed slats or ribs 3 disposed slightly apart as indicated. These slats or,ribs are attached tolongitudinal rails or stringers 4 which connect fixed heads 5. These heads 5 are formed of radial spokes 6 as shown in Fig. 3, and on the inner tached which form the heads of the barrel, as will be readily understood. These plates 7 are formed with central openings 8 fora p'ur pose which willbe more full y describcdhere; inafter. The centers of the spiders or heads 5are formed with hubs 9 having reduced necks 10 which are rigidly attached in the frame 1 by set screws 11 as indicated in Fig. 3. These hubs and necks are tubular as shown, so as to support a rotatable fan shaft 12. This shaft is rovided with a belt pulley 13 by means. of which it is rotated from an engine, and on the body of this shaft within the barrel, I provide a fan 14 the rotation of which will draw air in through the openings 8 in the heads, and force the same outwardly between the slats 3.

On the tubular necks 10 there is rotatably mounted a drum 15, which drum is formed of spider heads 16 the spokes of which are attached to rims 17. The outer edges of these rimsare formed into gear wheels by means of the teeth 18 asshown in Fig. 1, and these rims project beyond the slats 3 and receive a plurality of bars 19 which are disposed slightly apart and constitute can holders, for

they receive the cans between them as indi cated. These bars 19 are extended at the left, as indicated in Fig 3, and are provided with rollers 20 which have a function in ro tating the cans after they have been dipped.

with pinions '26 meshing with the aforesaid gear wheelsformed of the teeth 18. In this way, when the fan shaft is driven, the drum will be rotated at a reduced speed.

Under the drum and barrel there is provided a tank 27 which holds a bath 2% of Extending into the upper portion. of this tank from the right, as indicated in lacquer.

Fig. 5, there is provided a feed chute 29, and

the lower end of this feed chute is normally closed by a downwardly projecting gate 30 i which is formed on the forward end of a dipping plate 31, the said dipping plate being mounted at the edge of the tank to rock upon a pivot 32. On its upper side the free edge of the dipping plate near the, chute, is provided with an upwardly projecting rib 33 .ing extremities of the rods In.

which facilitates the operation of the dipping plate in taking the cans 31 one by one from the feed chute.

On its upper side the dipping plate is provided with a spring; plate 35 which is attiaehed rigidly to the upper side of the plate near its pivot 32. be other edge ol' this sprineplate 35 tends to hold itself slightly elevated from the dipping plate, and it is formed with a downwardly projecting wing In; which e tends through a slot 37 l'orined in the dipping plate shown. The wine 23o lies a short distance removed from the rib or lip 33:. so that a pocket is formed at this point which is adapted to receive a can.

The dipping plate iii is extended rearwardly as shown, and formed with a counterweight in the form of a transverse ar 338 which tends to hold the plate in the elevated position shown in l ig'.

The pivot 32 of the dippin; plate is in the form of a shaft which projects at the sides, and is provided with triangular shaped cam plates 39 which project upwardly so that they may come into the path of the project- As one olthese rods strikes the plates 3%), it depresses the dipping plate to the lower edge. of the chute 2.) so that the foremost can advances into the pocket between the rib or lip 213 and the spring plate 35.

to raise tho can to the lower side ol' thobua'rel, where it places it between two adjacent rods. The can will then advance with the rotating drum.

in order to retain the eans upon the drum when fed to it as described, the lower portion and side'ot' the drum is covered by a curved shield or guard plate 40 as indicated in Fig. 5. As the cans are passing over the upper sideot the barrel, they are lcl't uncovered. as they" will then hold themselves on the barrel by gravity. On the opposite side ot tho-drum where the cans are descending, a similar guard plate or shield sl is provided, which retains the cans and enables them to be delivered to a delivery chute l2 as indicated in In order to shield the lacquer bath from the dral't created by the tan, the underside ol the barrel is provided with a curved screen 43 which eov'ers the tank and protects it as suggested. in this way the loss 'ol lacquer by evaporation is reduced.

As soon as this rod has 1 )fLSSCti the dates 30 the weu'ht' 38 o erates i i s the can, the vertical wine 3t ol the spring plate operates as a stop for the can, which passes onto the dipping plate.

The level of the bath is kept sufliciently high so that when the can passes onto the dipping plate. as indicated in Fig. 4, the can will be completely immersed in the bath. The fact that the plate 35 is resilient, enables the plate to withdraw downwardly when struck by the rods it) as the advance.

Alter the cans have been led to the drum i from the feed chute, they are rotated lirstin one direction and then in the other, by means of a turning bracket 45 which is attached to the. l'rarne at 16. This lJl'tttiliCt has two curred segments 47 and 48, which are disposed respectively on opposite sides ol' the rollers .20. The faces of these segments lie in the paths of the faces of the rollers, so that they will rotate the rods it) as they pass the bracket. in this way, the walls which have been lacquered are rotated first in one direction and then in the other. This rotation makes the coating of lacquer more uniform on the on body, and also assists the drying operation. in this conneetioinit should be understood that the draft created by the fun operates to dry the lacquer as the cans pass l'noin the feed chute to the delivery eltute.

lnnnediately over the dipping plate lf'proride a wiper 49, the upper face ol which is l'ornied oi absorbent material, and this face is adapted to he strueh b the rods if) of the drum as it rotates, in, order to wipe oil the superlluous lacquer carried thereby. 'lhis wiper drains into the tank Jr.
